BOOT OR SHOE TREE.

Application filed June 28,

Be it knownthatl LFRANK J. MACDONALD, a citizen of the United States,residing at Akron, in the county of Sitlmmit and State ot'Ohio, haveinvented a certain new and useful Boot 01' Shoe Tree, of which the following is a specification.

This invention relates to means for supporting a last in selectivepositions to ta cilitate the building or treatment of a boot or shoethereon, and is particularly applh cable to the building up of rubbertootwear.

Its objects are to provide improved, simple means for the purposestated, to providea wide range of selective positions for the last andto provide means for preventing parts of the stock from wrinkling orsticking together before being placed in position in the boot or shoe,and for progres ively applying stock to the last;

Of the accompanying drawings: Fig. 1 is a side elevation of apreferredTo all whom it may concern:

embodiment of my device.

Fig. 2 is an end. elevation of thesame with the last-supporting memberin a different condition of adjustment. it i Fig. 3 is .a sideelevationot the same showing another adjustment and with a last in placeanda shoe inprocess of construction thereon. 1

Fig. i is side elevation showing another adjustment, with the work inplace.

Referring to the drawings, 10 is a table upon which are mounted a pairof brackets 11, 11 constituting a mounting for the parts hereinafterdescribed. Between said br ack ets is pivoted an arm 12 adapted tobemoved in a vertical plane from a substantially vertical position, asshown in Figs. 1, 2 and 4: to a substantially horizontal position, asshown in Fig. 3. Its hub is provided with friction washers 13, 18adapted tobe drawn against said hub by a thumb-nut let to brake themovement oi? said arm. The latter is also formed with a toe 1'5 andanabutment face 16 adapted to abut the table 10 to limit the movement ofsaid arm toward the,

vertical and horizontal positions respectively. i

Upon the outer end ot'the arm 12 is pivoted, for relative movement ofapproximately in the same vertical plane as said arm, a'bracket or arm17 formed with a bearing 1'?" transverse to the pivotal axes of 1921;serial No. 420,957.

18. 18 adapted to be drawn against said huh by a thumb-nut 19 to brakethe movement of said bracket said tl'iumh-nut acting through a clampingplate 20 held against rotation by dowel pins 21. 21 between said plateand said arm. a

A face 22 ot the bracket 17 is adapted to abut the arm 12 to limit themovement of said bracket in one direction and said bracket is providedwitha stud 28 adapted to abut the arm 12 to limit the brackets movementin the opposite direction.

A plate 2a provided with a perpencicular stem 25. is mounted in thebearing 1'? and is a friction washer between the plate 24; and thebearing 17 adapted to brake the turning of said plate. 2'? is ananti-friction thrust bearing interposed between the other end of thebearing 17 and the stem 25 to prevent the loosening of the nuts on saidstem and to avoid any braking: eitect other than that or the frictionwasher 26. 28, 28 are posts mounted perpendicularly upon the plate 24and adapted to fit into holes in the base or leg of a last 29 to holdthe latter in invertedposition upon said plate.

The outer end of theplate 24 is formed with an open slot M -parallelwith itsface in which are pivoted the inner endso f a pair ofstock-anchoring fingers 30, 30 adapted for movement from and toward eachother in the plane of said plate. the pivotal axes 30. 30 of saidlingers being substantially oppo; site the outline of the heel of thelast. The outer ends of said fingers are bent upward toward the last andcovered with rubberized fabric 30 30 beingthus adapted to receive andadhesively secure the ends of a termed sheet of rubber shoestock 31partially applied to the last, to hold the same temporarily out ofcontact with each other and the last and to prevent them from becomingwrinkled or deformed while the rest at the stock is being placed androlled, and finally, if desired, to carry said ends SHCCQF- sivelyaround the heel oi. the lastto apply the stock thereto progressively.32, 32 are stop pins mounted upon the plate 24 and adapted to becontacted by the fingers 30 to limit their movement away from eachother.

the elastic stock- 31 will be slightly-oft-cengiven numerousworkingpositions, with a "tus-in the position shown in Fig. 1, for

a moment about} said axis.

sufiicient frictional resistance against movement therefrom as topositions in Vwh ch the-lighter operations in building rubber footwearare performed and positive resistance against the heavier forces appl edin the building operation. I

It will be observed that with the apparaexample, downward pressure uponthe stock around the edge of the sole exerts a force which is resistedby the abutment of the face 22 otthe member 17 against the member 12,and as such force is substantially toward the pivotal axis of the member12 it does not represent a substantial turning In Fig. 4 there ispositive resistance against the force of the stock as it'is stretcheddown overthe last and attached to the fingers 30. As illustrating themanypositioning possibilities of this device, it will be observed thatthe last may be turned sole upward, about the y axis of the bracket17,'at the low elevation represented by Fig. 3, or it may be turned soleupward at the higher elevation repre sented by Figs. 1, 2 and 4 and thelast may be turned through a complete revolution aboutthestem 25. p

The details of construction may be varied without departing from thescope of my in vention, and I do not wholly limit my claims to thespecific construction shown.

I claim: i

1. A boot or shoe tree comprising a mounting, a swinging arm hingedthereon and having a positively limited swinging range 'fromasubstantially horizontal to a substantially upright position,v a secondswinging arm hinged on the outer end of the first said arm, in outwardextension thereof and on'an axis substantially parallel with;

the hinge axis of the first said arm, said second arm having apositively limited swinging range of approximately ninety degrees, and alast-supporting member adapts ed to hold a last in fixed relationthereto and pivotally mounted on said second arm in outward extensionthereof and on an axis transverse to that of the latter, and-fixedwithrelation to said second arm.

2. A boot or shoe tree comprising a mounting, a swinging arm hingedthereon and having a positively limited swinging range from asubstantially horizontal to a substantially upright position, a second,relatively short swinging arm hinged thereon on an axis substantiallyparallel with thehinge axis of said first'arm, and a lastsupportingmember adapted to hold a last in fixed relation thereto and pivoted onsaid second arm, on an axis fixer wvitli relation to said second arm,the second arm having a positively limited swinging range such that saidlast-supporting member and a last thereon may be swung over-centerwithrelation to gravity and to the hinge of said second arm when said firstarm is in either its horizontal or its upright position, v

If A boot or shoe tree comprsing a mounting, a series of swinging armshinged to each other and the first hinged to said mounting, on parallelhinge axes, and a last support pivoted on the outermost one of said armson an axis transverse to said hinge axes, each of said arms having apositively limited swinging range about its hinge, said arms being soproportioned and their swinging ranges being such that they may beturned to positions in which they will be positively stopped against aforce applied to said last support toward said mounting, and topositions in which they will be positively stoppedagainst a forceapplied to said last support in a direction transverse to said axes andat right-angles to the combined lengthof sa d arms.

4. A boot on shoe tree comprising a mounting, a swinging arm hingedthereon the second arm, and when the second arm is at the other. limitof its swinging range such a line will its hinge axis. v

5. A boot on shoe tree comprising a mounting, a swinging arm hingedthereon and having a positively limited swinging range from asubstantially horizontal to a substantially upright position, a secondswinging arm hinged on the outer end of the first arm on an axisparallel withthe hinge axis of the latter, and a last support adapted tohold a last in fixed relation thereto and pivoted on said second arm,-on an axis fixed pass on the other side of with. relation to said secondarm, the relation of said parts being such that with said first arm ateither limit of its range a last mounted on said support may be revolvedon the pivot of the latter with its sole substantially in either avertical or a horizontal plane.

6. A boot or shoe tree comprising a lastsupporting member and astock-anchoring member 3ivoted thereon on afixed axis transverse to thesole of the last, said stockauthoring member being adapted to haveattached thereto a piece of stock partly applied to the Work and to beturned on its pivot, without movement of the latter, to :npply saidstock progressively to the last.

7. A hoot or shoe tree comprising a lastsupporting member and astock-anchoring member pivoted thereon on a fixed axis transverse to andadjacent the outline of &

the sole of the lost said member having a positively limited, pivotalrange and being zulepteth at the limit 01' its range, to hold off-centerpiece of stool: partly applied to the last, and to be turned past-centerfrom said position to apply said stock progressively to the last.

8. A boot or shoe tree comprising a lastsupporting member and a pair ofpivoted stock-anchoring members adapted to anchor the ends of the stockat a distance behind the heel portion of the last and separately to beturned about said heel portion progressively to apply the stock thereto.

In Witness whereof I have hereunto set my hand this 22 day of June,1921.
